Abstract
Positron scattering cross sections, used for modelling particle transport in various media, are difficult to gather experimentally. As such, various cross section calculation methods have been developed to varying accuracy. The IAM-SCAR+I method has been improved upon recently to fulfil the optical theorem and the results for two important simple molecules, N2 and O2, are presented here. These results are compared to literature and our findings are comparable in most impact energy ranges.Graphical abstract
